SPECIFICATION forming part of vLetters Patent' No.v 237,612,dated'February 8,*1881.

` Application filed June 21, 1880. (Nomodcl.)

To all whom it may concern:

Be it known that 1,- GUsTAv SCHWARZWALD, ofthe city, county, and Stateof New York, have invented certain new and useful Improvements inApparatus for andl Method of Producing Polychromatic Brints, of fwhichthe following is a speciication.

This invention has reference to an improved machine and method ofproducing designs in Io any desired colors on a dark or light ground ofpaper, wood, metal, or other fabric, whether in straight lines or invariously-formed patterns, for the purpose of obtaining polychromaticeifects, which were heretofore not obtainable in theprinting orlithographie arts.

The invention consists in applying to any object which has been partlyor entirely covered with a layer of adhesive materialv pul verizedcolors by means of a'vertically-movzo able distributer. The distributeris constructed of perforated shelves, which support a series ofcolor-tubes that are arranged according to any suitable design andclosed at their lower ends by bolting-cloth. The finely-pulverized z 5colors are deposited by the sudden concussion ofthe distributer with apattern-frame placed upon theobject,-and distributed evenly eithermechanically by properly-constructed brushes or sweeps yor pneumaticallyby air-pressure'.

3o By a repetition of` this process a variety of colors and any desiredblending of the 'same may be obtained.

In the accompanying drawings, Figure l represents a verticallongitudinal section of my improved machine for producing polychromaticprints. Fig. 2 is a sectional side elevation of the sameV with twocolor-distributers -ofdifferent construction. Fig. 3 is a verticalcentral section of one of the color-tubes on 4o anenlarged scale. Fig. 4shows two crosssections of differently-shaped tubes. Fig. 5 represents asectional top view of the machine, showing the color-distributer and thereciprocating carriage for the pattern-frame. Fig.v 6

is a top view of a pattern-frame with curved portions. Fig. 7 is adetail vertical section of the distributer and color-tube, shown inposition on the pattern-frame for depositing the color. Figs. 8 and 9are respectively a top viewand a vertical longitudinal sectionof'the 5omechanism for operating the color-distributing brushes or sweeps;vandFig. l0 is a top view of a portion of a label or other print produced bymy improved method. l

Similar letters of reference indicate corresponding parts.

Referring to the drawings, Ais'thevsupport ing-frame of my improvedmachine for producing polychromatic prints. lThe frame Ais provided withlongitudinal top rails, c,`on which 6o is guided a reciprocating carriage, B, the carriage being operated either by hand or power, asdesired.

Upon the carriage B the platen of `the rmachine is arranged, and the'paper or other ob- 65 ject to be produced in-colors placed upon theplaten, the paper having lirst been covered, either partly or entirely,with a layer or covering of any suitablefatty ink or an adhesivesubstance. This layer forms the ground upon 7o which all the colors arelaid on in succession.

Upon the carriageB and the paper or other object to be printed is placeda patternframe,

C, composed either of parallel bars which taper toward their uppernarrow edge or of angular oblong curved strips, as shown in Fig.

6. A pattern-frame, C, with straight strips is employed whenever thecolors are to `be laid on in right lines, a pattern-frame with angularor curved strips whenever a special design is 8c to be produced. Thepattern-frame O is secured by clamp-screws or otherwise to an openframe, D, which is hinged at one side to the carriage B, and provided atthe opposite side with a handle for readily raising or lowering 8 5 thepattern-frame in removing and inserting the paper to be printed upon.

The frame A is extended above the carriage B, and supports either abracket-shaped arm, A', or a braced top part, A2, which serves to 9oguide and support the vertically-movable rod E of the color-distributerF, which isapplied to the lower end of the rod E by suitable adjustablefastening devices. This color distributer F forms an essential elementof my 9g invention, and is Worked either by a hand-lever and weight, orby a lever-,and-treadle connection, or by power and suitable workin gmechanism, so as to be quickly lowered upon the pattern-frame of thecarriage or raised therefrom.

The color-distributer is constructed of two perforated shelves, b b, inthe holes of which a series of color-tubes, F, is supported. The

- lower part of the color-tubes F is made of design to be produced, theybeing placed closer to each other or farther apart, according to thesize of the surface to be colored, so that any desired tint can beproduced. By lowering the color-distributor F on the pattern-frame asmall quantity of color is dropped onto the paper on the platen by theconcussion of the distributer with the pattern-frame. After the color isthus deposited within the strips of the pattern-frame the distributer israised by the lifting mechanism away from the frame.

As the quantity of color discharged by each color-tube is very sm alland deposited in such a manner as to cover only a small part of thesurface of the paper,the next step is to produce the uniformdistribution ofthe colors over the en tire surfaceofthesame.Thisisaccomplishedeither mechanically by means of brushes or sweeps,which are operated by hand or by suitable mechanism, or pneumatically byair-pressure. For the latter purpose the color-distributer is closed atthe top, so as to form an air-chamber, which is connected by its hollowguiderod and a suitable hose with a fan or other air-compressing device.rlhe air is allowed to enter the distributer or is shut off by a valveof the guide-rod, so as to put on or interrupt the air-pressure. Thelower part of the colordistributer bears, by a felt or other elasticfacing, tightly upon the pattern frame C, the outer frame, D, of whichis also lined with felt, so as to bear tightly upon the strips of thepattern-frame. The air is evenly distributed in the air-chamber abovethe color-tubes by a horizontal diaphragm, (shown in Fig. 2,) andconducted through the holes of the shelves not taken up by color-tubesinto the spaces inclosed between the strips of the pattern-frame, thebottom of the color-distributer, and the paper on the platen. rlhe airacts upon the colors deposited from the tubes by the concussion,distributing them uniformly over the entire surface of the paper betweenthe straight or curved strips of the pattern-frame. This arrangement ofdistributing the colors is shown clearly in Fig. 2, while the method ofdistributing the colors by brushes or sweeps is shown in Figs. l and 5.The brushes Gemployed for this purpose are covered with beaver-fur, andagain covered at those portions which are not required for spreading thecolors with bands of paper, leather, or other suitable fabric. The brushis drawn by hand once or twice over the pattern-frame, and locked afteruse to retaining hooks or clasps of the hinged frame D, so as not to getdetached therefrom when the frame is thrown up for placing another sheetin position. The soft fur ot' the beaver-skin not only takes up thesurplus color, so as to use it for the next sheet, but it produces alsoa perfectly even distribution of the colors over the surface of thepaper. If desired, the distribution of the colors may also be producedby fur-covered revolving brushes which are set into a perforated frame,which perforations correspond with those of the shelves of thedistributer, the brushes being rotated by reciprocating rack-bars whichmesh with small pinions at the upper ends of the brush-spindles, asshown in detail in Figs. 8 and 9. For most purposes, however, thefur-brushes operated by hand are sufficient, though for largermanufacturing purposes the brushes may be so constructed that they canbe worked by power. After the colors are laid on the carriage is drawnsidewise, the hinged pattern-frame thrown up, and the paper removed. Anew sheet is then placed in position and properly registered thereon,the pattern-frame brought down on the paper and carried with thecarriage into position below the distributer. The color is thendeposited by lowering the distributer, and finally evenly distributedover the surface to be colored by the brushes, as described. In thismanner a variety of tints, in right or intersecting lines and in anydesired pattern, and in plain or blended colors, may be produced, andthus an infinite variety of polychromatic designs for fancy labels,checks, and other purposes obtained.

The advantage of the apparatus consists, mainly, in the fact that anynumber of different colors can be laid on with a perfect register by011e operation, and thereby a more variegated effect be obtained.
